Patrick Bommarito is a 35-year-old openly gay American who lives in Tokyo.

He contracted HIV 12 years ago by having sex with an HIV-positive man in New York, shortly after breaking up with his Japanese boyfriend, with whom he had lived for six years.

"On my birthday in October 1988, a condom broke during sex and I got it then. That's how I got it, one time, one broken condom," Bommarito said. "It wasn't a surprise . . . but I had plans and they had to change."
